Answer:
0.4344A
Explanation:
From Ampere's law, it can be shown that the magnetic field B inside a long solenoid is
Where
B= Magnetic field strenght at distance d
I= current
Permeability of free space ()
N= Number of loops
Our values are defined as follow,
T
As a current required to become 104 times the Earth's magnetic field is required, we use B '
<em>Therefore is needed 0.4344A in the solenoid to produce a magnetic field inside the solenoid, near its center, that is 104 times the Earth's magnetic field.</em>
The answer to this question is dropping it on a hard surface.
Geosphere, hydrosphere, atmosphere, and biosphere.
Therefore, the correct answer is D.
The complete options are;
A. The average kinetic energy of their particles is the same.
B. The total kinetic energy of their particles is equal.
C. Heat flows from the larger object to the smaller object.
D. Heat flows from the object with higher potential energy to the object with lower potential energy.
Answer:
Explanation:
From the relationship between average kinetic energy and temperature, we have the formula;
E_k = (3/2)kT
Where;
k is a constant known as boltzmann constant.
T is known as temperature
We can see that at the same temperature (T), kinetic energy will remain the same because from the formula, E_k depends km only the temperature.
Thus, average kinetic energy of their particles saying that.
Answer:
Explanation:
We are asked to find the acceleration of a box.
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The mass of the box is 5 kilograms. There are two forces applied: a 25 Newton force and a 50 Newton force, both applied right. Since they are applied in the same direction, we can add them.
- 25 N right + 50 N right = 75 N right.
Now we know 2 of the variables in the formula:
- F= 75 N or 75 kg*m/s²
- m= 5 kg
Substitute the values into the formula.
We are solving for a, so we must isolate the variable. It is being multiplied by 5 kilograms. The inverse operation of multiplication is division. Divide both sides by 5 kg.
The units of kilograms cancel.
The acceleration is in the same direction as the force, so the acceleration is <u> 15 meters per second squared to the right.</u>
